Cryogenic System Cooldown Projection based on Full Compressor Power Starting on January 17, 2012
.5 to 1 MW – Nov 23, 2011 through Dec 18, 2011 (temporary peaks up to 2 MW)
Scrub of RHIC rings and cryo plant, 14 atm pressure test of blue sextants 2/3 and 8/9 M-lines. Main compressor testing and scrub.
2.8 MW – Dec 19, 2011 through Jan 16, 2012 12/19/11 Start 45K cooldown of cryo plant 12/20/11 Start 45K wave in both RHIC rings 12/31/11 First liquid helium delivery, 1006B 01/07/12 Second liquid helium delivery, 1006B 01/14/12 Third liquid helium delivery, 1005R 6 to 8 MW – Jan 17, 2012 through Jan 22, 2012 01/17/12 Start 4K wave in Blue ring, Hi potting (3 days) 01/20/12 Estimate blue ring cold and stable, soak complete, ready for magnet powering.
01/20/12 Start 4K wave in Yellow ring, Hi potting (3 days) 01/21/12 Fourth liquid helium delivery 01/23/12 Estimate yellow ring cold and stable, soak complete, ready for magnet powering. 5 MW starting on Jan 23, 2012 01/23/12 Start T7 turbine

I'm still waiting for confirmation from Linde for the liquid helium delivery schedule. They are no longer able to meet our peek demand of 4 trailers in a one week period. They should be able to give us one trailer a week starting on December 31st, so we expect to have all the helium we need, on time, but we will have to store most of it in the dewars outside 1006B. This will result in our 4K cooldown being a little less stable and predictable than it has been for the past few years when we received all of the helium at 1005R over a short period of time. Because of this, I expect the 4K cooldown will take a least one additional
day.

For Run 12 the PAC recommends the following (in order of priority): • 5 weeks of running with polarized proton collisions at 200 GeV.• 7 weeks of running with polarized proton collisions at 500 GeV. • 5 weeks of running with Cu+Au collisions at 200 GeV. • 3 weeks of running with U+U collisions at 193 GeV.
For Run13 the PAC recommends the following (not in order of priority):
• 12 weeks of running with polarized proton collisions at 500 GeV. • 5 week of running with polarized proton collisions at 200 GeV. • 7 weeks of running with Au+Au collisions at full energy.
